Rebecca Romijn, Jerry O'Connell Welcome Twin Girls!

Rebecca Romijn and Jerry O'Connell, her husband of a year and a half, have welcomed twin girls, Howard Stern announced on his Sirius radio show Monday morning.

News that the two were expecting first broke in July. A month later, O'Connell joked that he was already feeling protective of his unborn daughters.

"Just the fact that they're girls, you know?" he said. "I don't want them to date. They're only allowed to date men who run countries. They're only allowed to date men who are heir to the throne or are currently running a nation."

It wasn't easy for ger to get pregnant, but Rebecca Romijn - who skipped pal Stern's wedding to Beth Ostrosky because of bed rest - revealed that the twin girls were ultimately conceived without the help of in vitro fertilization or drugs.

"A year ago, we tried [fertility drug] Clomid for a couple of months unsuccessfully," she said. "But by the second month, I was like, 'Ahhh! I hate this!' I think when you start messing with your own hormones, it's crazy-making."

As for O'Connell, we're guessing he had no trouble doing his part. Dude was seeing Rebecca Romijn nude on a nightly basis, after all.
